Bought to install my HT3550. The fittings are perfect for the projector. The only complaint I have is that the ball joint doesn't lock the projector exactly where it should be. Once the latch is secured, there will be a slight "slip" as the mount/projector is released. This is important because when installing a projector we are talking about millimeters that can make a difference whether the image is square in relation to the screen or not. This mount has been "tuned" for a long time, but it didn't work out. There may also be times when my projector is not 100% perpendicular to the screen, but I would expect the mount to be secure enough to stay where it is needed.
